Soon, obesity pill that re-wires brain into feeling full (TOI April 07, 2013)
Scientists have inched closer to developing a new diet pill that can prevent obesity by "re-wiring" appetite control in the brain.
A new study, published in the Journal of Neuroscience, has identified a population of stem cells capable of generating new appetite-regulating neurons in the brains of young and adult rodents.
The discovery by researchers at the University of East Anglia (UEA) could offer a long-lasting solution to eating disorders such as obesity.
They established that a population of brain cells called 'tanycytes' behave like stem cells and add new neurons to the appetite-regulating circuit of the mouse brain after birth and into adulthood.

Stem Cells Fill Gaps in Bones (Science Daily April 4, 2013 )
Autologous stem cells have been found to accelerate and boost the healing process. Surgeons at the RUB clinic Bergmannsheil have achieved promising results: without stem cells, it takes on average 49 days for one centimetre of bone to regrow; with stem cells, that period has been reduced to 37 days.
Today, the arm or leg is stabilised in an external support, and a transport wire is pulled through the marrow of the intact part of the injured bone. Once the soft tissue surrounding the injury is healed, the surgeons cut the healthy part of the bone into two.
Using a sophisticated cable-pull system, the previously detached part of the bone is slowly pulled either downwards or upwards along the gap in the bone until it arrives and docks at the other end. During the pulling stage, the periosteum of the bone that had been pulled apart had been continuously stretched. Thus, a periosteum tube is created in the gap behind the relocated portion of the bone. Inside that tube, the new bone can regenerate.
Surgeons at the RUB clinic Bergmannsheil attempt to optimise the healing process by applying autologous stem cells therapy. Depending on the requirements, stem cells are capable of evolving into different types of tissue cells, including so-called osteoblasts -- cells that are responsible for bone formation. Adult stem cells such as are deployed in the process can be found in the bone marrow of adults. "We harvest them by inserting a hollow needle into the iliac crest," explains PD Dr Dominik Seybold, managing consultant at the clinic.
